Swedish Estonia

Swedish Estonia was a possession of Sweden that existed from 1558 to 1710, with Reval (Tallinn) serving as its capital. In the wake of the breakup of the State of the Teutonic Order, the Baltic German nobility asked King Eric XIV of Sweden for protection, leading to Swedish intervention in the Livonian War and the subsequent Swedish annexation of Estonia. In 1629, southern Estonia was incorporated into Sweden during the Polish-Swedish Wars, and Sweden conquerred the island of Saaremaa from Denmark in 1645 during the Torstenson War, completing its conquest of Estonia. In 1710, the Russian Empire conquered Estonia from the Swedes during the Great Northern War, and Russian hegemony was formalized in 1721.
